Solvent Targeting, Avoidance And Recovery Trials (Start), Kealan Allen

Theses

Solvent is the largest-volume raw material used at Janssen Pharmaceutical (Ire) Ltd. Over 2.2 million m³ were used in 2004. The top 13 solvents make up 99% of this amount. There are two main uses for solvent on site, processing and cleaning. Processing uses 55% of the total solvent used on site, cleaning uses the remainder.

Waste solvent forms the majority of the hazardous waste produced at Janssen. Three treatment options exist at present for this waste: incineration, recovery for reuse and energy recovery. All of the hazardous waste produced on site must be exported for these treatment options, …

Evolutionary Algorithms For Production Scheduling, Pio Fenton

Theses

The permutation with repetition representation is a powerful representation primarily used in the GA-JSSP domain. Recently, attention has shifted from this representation for simple GA and towards JSSP resolution using messy GA. This work returns to the permutation with repetition representation for simple GA with the intention of exploring some previously unexplored aspects. A new 1-point crossover operator is introduced which is shown to be more successful than the current standard operator for this representation. A technique known as morphogenic computation is employed with this representation for the first time and a thorough analysis of its performance is presented. While …

Electronic Mathematics, Aidan O'Donoghue

Theses

Recent times have seen an explosion in the use of interactive technologies in the delivery of learning content to students in all educational sectors in Ireland. This expansion has led to the creation of modem day phenomenons such as global and ‘teacherless’ classrooms.

The research study I have undertaken is to determine if students perform to the same standard when learning through an interactive educational software application as opposed to a more traditional setting of learning ’through’ a teacher in a classroom. The application being developed for this study enables students to learn the ordinary level leaving certificate mathematics course …

Development Of A Service-Oriented Communication Platform For Heterogeneous Voice Over Ip Networks., Aisling O'Driscoll

Theses

As broadband services have become more widespread in recent years due to a variety of government initiatives and the establishment of Wireless Internet Service Providers, user requirements have evolved and the market has become more competitive. Whilst this is beneficial for consumers it means that Internet Service Providers must offer a more diverse range of services coupled with standard broadband packages to distinguish themselves from their competitors, generate new revenue and strengthen their competitive advantage. Therefore many providers are looking to Service Oriented Architectures (SOAs) to provide communication platforms, enabling services such as Voice over IP (VoIP) along with other …

Zero Effluent Stretch Target (Zest), Orla O'Connor

Theses

The goals of this project were to assess the viability of avoiding water use and of “cascading” water uses, i.e. using outlet water from one process in another activity, possibly with some purification, including the upgrading of the final effluent stream for internal reuse. Water use has been inventoried at FMC Biopolymer, Cork. Avoidance and reduction measures were identified that could reduce water consumption from 49m /hr to 19 m /hr (a reduction in excess of 60%), with an annual saving in excess of €350,000. These projects were assessed for feasibility and implementation. Potential streams that could be subject to …
